Master Guide to Nomad Knife Case Hardened Blue Gem Patterns & Tier Rankings

The higher the percentage of blue color present in a Blue Gem, the more highly the pattern index is regarded within the community. Ideally, a Tier 1 Blue Gem should have a full blue playside, with no traces of yellow being present. The amount of blue in the backside isn't taken into account when ranking Blue Gems in CS2.
A Tier 1 Blue Gem, which features the most amount of blue on the playside, is considered the most valuable, with a correspondingly higher price point. In comparison, a Tier 2 Blue Gem, although still valuable, will have a lower price point than a Tier 1 Blue Gem. Similarly, a Tier 3 Blue Gem will be less valuable than a Tier 2 Blue Gem, and so on. Therefore, the rank or tier of the Blue Gem is an important factor in determining its value.
